Lowering with torsion bars - how low can you go

Lowering the front end of my car by loosening the bolts (obviously with the front end off the ground)

How loose can the bolts be with the car in the air? So how much is to much

I know different bars can be lowered further and it depends on the spring rate of the bar

Currently have 1.03 bars

The adjusting bolts have to make contact with the adjuster levers when the suspension is at full extension. If they don’t, and you go to full extension on the street, the bolts can shift and come off the adjusters when they’re unweighted and that won’t be good when the suspension is reloaded.

Next issue is that you need to have enough suspension travel for the spring rate. With 1.03” bars you need to have about 1” between the bumpstop on the LCA and the frame at ride height otherwise you’ll constantly be bottoming the suspension. How low that actually is depends on how tall your bumpstops are.

You can back those bolts out till they fall out on the ground, it'll be fine mechanically.

No, it won’t because if the adjusting bolts aren’t in contact with the levers the LCA is not fixed to the torsion bar socket. So the LCA will rotate freely on the socket and the torsion bar won’t be loaded.
